Background service on a Glassfish server

is it possible to run a background service/daemon on a glassfish server?

Best,

T

Edit: To clarify things: I mean a daemon like a windows service, that runs in the background and gets triggered by an ev开发者_JAVA技巧ent.

Glassfish is Java EE container, so you can deploy any Java EE service: EJB, Webservices, JMS, etc. If you don't want to be bound by Java EE restrictions you could develop Java application, deploy it as OSGI bundle and listen to any events available to Java Runtime.
